Assertion on 'r5r_core' failed

[keyingtang]

Brief description of the problem:

Hi all, I have the same error when running every function that takes 'r5r_core' as an assertion. For example:

> # calculate a travel time matrix
> ttm <- travel_time_matrix(r5r_core = r5r_core,
+                           origins = poi,
+                           destinations = poi,
+                           mode = mode,
+                           departure_datetime = departure_datetime,
+                           max_walk_time = max_walk_time,
+                           max_trip_duration = max_trip_duration)
Error in travel_time_matrix(r5r_core = r5r_core, origins = poi, destinations = poi,  : 
  Assertion on 'r5r_core' failed: Must inherit from class 'jobjRef', but has class 'NULL'.

Could you please help me solve this problems? Many thanks!

Could you please run r5r::r5r_sitrep() and paste the output in a comment below ?

The problems seems to occur in the step of creating the r5r_core object. Here's an explanation on how to do it.

Could you please paste the code you have used to build the r5r_core object?

[keyingtang]

Hi @rafapereirabr I am running r5r.Rmd in vignettes folder, so it' exactly the same as the one on the page you shared.

# Indicate the path where OSM and GTFS data are stored
r5r_core <- setup_r5(data_path = data_path)

[rafapereirabr]

could you please paste the code you're using? I mean the code from the beginning of loading libraries, pointing to data path etc etc etc

[keyingtang]

data_path <- system.file("extdata/poa", package = "r5r")
list.files(data_path)
Here is the output (I can load all the files such as poi):
[1] "fares" "poa_elevation.tif" "poa_eptc.zip"
[4] "poa_hexgrid.csv" "poa_osm.pbf" "poa_points_of_interest.csv"
[7] "poa_trensurb.zip"

Then I use this line to create r5r_core object, it also runs well:
r5r_core <- setup_r5(data_path = data_path)

But then I want to call functions using r5r_core as an assertion, it showed the error:
Error in accessibility(r5r_core = r5r_core, origins = points, destinations = points, :
Assertion on 'r5r_core' failed: Must inherit from class 'jobjRef', but has class 'NULL'.

[rafapereirabr]

could you please try running this code and paste the output below?

library(r5r)

# build transport network
data_path <- system.file("extdata/poa", package = "r5r")
r5r_core <- setup_r5(data_path)

# load origin/destination points
points <- read.csv(file.path(data_path, "poa_points_of_interest.csv"))

departure_datetime <- as.POSIXct( "13-05-2019 14:00:00", format = "%d-%m-%Y %H:%M:%S" )


ttm <- travel_time_matrix(
  r5r_core,
  origins = points,
  destinations = points,
  mode = c("WALK", "TRANSIT"),
  departure_datetime = departure_datetime,
  max_trip_duration = 60
)

head(ttm)

Hi, I have run this code and I met a bomb which is the same as Issue#315 (fatal error). Maybe it's a Mac problem.
But I managed to import r5py so I will try using it now.
Thanks a lot!

[rafapereirabr]

thanks for letting us know. Issue #315. closing this issue for now.
